B e it known 'that I HARRY' C.INNns, a

tates, and a 'rident of 1Hartwell,"in the county of Hamiltonl andv State of. Ohio, whose ost-oliice address is.l

artwell, Ohio, 'have invented new., and useful Improvements in -Waterproofing Construction, 'of which 4the following is aspecication.

My invention relates to methods of water.-

proong. 'It is especially adapted for use 1n waterproofing building structures, reservoirs, br1dges, subways and-other sub-level constructions,` etc. Heretofore in the. art of waterproong such structures it has been the practice to apply se arately to the surface to be waterproofe a number of'plies of wate lroofed paper: or waterproofed felt,

and ben them together by suitable baminous waterproofing material, such as asphalt, coal tar, etc. In this wayfhaving determined 'the thickness of the waterproofing desired it was the practice to first apply an tofbe waterproofed, then aply or layer 'of felt or paper saturated with a waterproofing compound, then another layer or bon of waterprooiin material, then another ply of waterproofe felt or waterproofedpaper, and contmue in this way the applicatlons of the alternate layers of waterproofed felt or'- waterproofed paper andthe bondlng layer of waterproofing material until the desired thickness had been obtained. This has not been found to give entirev satisfaction because-the method of application permitted of many air spaces between layers and 'it was i diicult to obtain a uniform application of the waterproof bond'la'yer. It was an ex pensive operation, not only `taking cons1der- 'able time for application, but 'requiring the application of a number of plies of waterproofed felt or waterproofed paper to obtain the desired thickness. The paper or felt used in and of itself served no particular use in the waterproofing except as a carrier or binder to su port the waterprooiing material so as too tain the desired thickness of the waterproofing material. My improved waterproofing material is manufactured -to l the desired thickness, size and shape at the factory in the form of boards or slabs, shiplped to the point of application and then app ed to the surface to be waterproofed.v

ing having'been determined in. advance, it" i 1s bu1lt 1n separate board like unitseand ap# l plied to the structure.'

waterproofed. My methodof application of my improved I l waterproong facllitates the' application, j

cheapening the cost and at the same time makmg a more thorough and complete waterproofing structure.

In the drawings, Fi 1 is -a i rspective d. view of my waterproo n slab. f ig. 2 is a sectional view through lme 2, 2 of Fi 3,

lshowing one method of application. YF1 3 is a pers ective view of -my waterproo ngv slabs app ie'd. Figs. 4 and -5 show method of applicatlon to a corner. Fig. 6 is a. mod iiication of my vwaterproofing slab. Fig. 1

shows a slab lor Aboard of my improved waterproofing material. The slab or boardl is formed preferably'of a thick layer o f asphalt A, which I have preferably come l bined with suitable iller of a characterthat permits of its being saturated -by the asphalt. Thls asphalt compound is preferably tempered so that it will not crack at low tem-V peratures or become too plastic at high temfperatures.l B, B, are layers of felt or paper,

preferably saturated with an asphalt com pound. Any suitable bituminous materials,

coal tar or similar waterproofing materials f could be used in making my improved e waterproofing board or slab in place of the asphalt. The structure may be of any dements of'its use to achieve the results de- .v

sired thickness, depending upon the'requiresired. The thicknessmay be varied b makv ing the layer of asphalt of anydesire thick# ness and the layers of saturated felt or saturated paper of such thicknesses may be found necessaiyftomake a board like structure and of such number as desired. In

' practice I prefer, however, to have the layer Aif twolayers of felt or more are use terial, except in so far as it is Saturated which the waterproo n with a Waterproofing compound.. Figs. 2, 3, 4 and 5 show methods of application. In Fig. 2, 6 is a concrete surface; I referably rst appl a priming coat toA this concrete surface, t 4en an adhesive coat of suitable material depending'u on the material of slab has been manufactured, that is, if 1t is manufactured of asphalt I apply an asphalt paint or other suitable waterproof adhesive material, andif the slab or board is made of coal tar I prefer to apply creosote oil or similar material having an alfinit for the coal tar so as to make a perfect a hesion. Having applied the adhesive I then apply thel slabs of waterproofing sometimes direct to the adhesive coat and sometimes by also applying' an adhesive coat on the exterior of the slab which is to contact with the adhesive coat on the concrete. It is not essential in all cases to apply the priming1 coat or the adhesive coat. If desired t e slabs may be placed in position and other suitable means provided for holding them there. If the waterproofing is to be used between two surfaces Where it would be held rigidly in place by the materials on each side of it the adhesive coat could be omitted if desired. Of course in many vplaces it would not be necessary to use a priming coat. This is used primarily for concrete surfaces. The slabs 1, 2, 3 and 4 being laid in position as shown in Fig. 3, I then mop along the adjacent portions near lthe joint C forcing into the joint C asphalt or other bituminous material that I mop with, then apply a strip D of felt or paper saturated with a waterproofing material so as to overlap adjacent ends or sides of two or more of the slabs thereby covering the joints. When the joints have all been covered in this way I then mop over the entire surface with asphalt or other bituminous material and the waterproofing is finished. If there are any corners I waterproofrthein as shown -in either Fig. 4 or 5. kIn Fig. 4 slab 1 rests upon or abuts against slab 2; first, however, I prefer to coat the top of slab 1 or the surface of slab 2 where they are to contact with an adhesive coat of waterproofin material. When they have been set in position I then Lumens take a section or'slab or my waterproofing in Fig. 4 wherein 3 is ajslab bent at right angles. I then mop the cornersurfaces of slabs 1 and 2 with a bituminous material, place slab 3 in position and then mop over the surface of [slab 3 the edges thereof and material, heatit and then bend it as shown the surface of slabs 1 and 2 as shown with a Waterproofing material and the corner is finished. If desired a piece of waterproof paper or felt 7 could be placed in the corner before the slabs 1 and 2 are placed in position and caused to adhere to slabs' 1 and 2 by a coatin of adhesive material. In Fig. 5, I have siownjanother method of waterproofing a corner wherein the slab3 bent at right angles is placed in the corner, then the adjoining slabs l and 2 of the waterproofing is brought intocontact with the slab 3.V I then mo over the corner and the adjacent slabs witi a bituminous material.

apply.a layer'D of paper or felt saturated with waterproofing material, press it into the corner as shown so as to overlap thel joints between slabs 1 and 3 and slabs 3 and slab overlapping a portion of the next adjacent slab. Any form of carpentering joint may be used in this way.

Wherever herein I have referred to the l use of asphalt or asphalt compound, I would have it understood that' any suitable bituminous or other waterproofing material could be used.

I claim: 1. A waterproofing construction consisting of a layer of preformed relatively rigid block like waterproofing slabs, composed of layers of bituminous saturated exible sheets bonded together by a relatively thick layer of bituminous material and compressed into a block like slab, said slabs all arranged in the same plane with adjacent edges abutting so that corresponding sheets of iexible material in adjacent slabs will be in substantially the same plane and the corresponding layer of bituminous material in adjacent slabs will bein the same plane, a bituminous material between adjacent slabs cementing the abutting edges of adjacent slabs all so arranged that corresponding layers of flexible sheets in adjacent slabs are substantially continuous and. the corre-y sponding layers of bituminous material in 'adjacent slabs are substantially continuous.
